Throughoutr the several viewslike reference charactersrefer tosimilar parts andthe'numeral It) designates a case open at the'top and having side Walls l2 and M. A cover member [6 hinged at one endof case lil by means ofa pin I8 is adapted to cover the case: and: is provided adiacent its forward end with a transversefi'slot 2!] through which the tape T is fed. Therear side of slot is formed by an-intnr-ned arcuate lip 22 which serves as a guide for the-tape as hereinafter setforth,

7 A: vertically disposed partition-2'4 spacedapart from the front end of case-lilserves to form 'a water compartment 26 into which is immersed a wick 2B. This wick 28 comprises a fabric wick member 3i] provided with a resilient backing plate 32 which is adapted to be adjusted so as to vary the tension of the upper portion of the wick member 30 against the arcuate lip 22. will be noted that the lower portion of wick 28 is fitted between partition 24 and the spaced apart vertical disposed lugs 34. When so positioned the water in compartment 26 will be fed to the upper extremity of the fabric wick memb61 30;-SOfaS0 GOnta7GU and moisten the tape T passing therebetween. While the tape material isme latively stifi yet if the tensionexerted by the plate 32 too great, it will cause the tape to buckle andjamb; the machine. It is therefore necessary that the operator adjust the spring member- 32- to the exact tension required to properly moisten the ummedsurface of tape-Twithoutrestricting? its free movement from themachinec M I v Referring to Figs. Land 2 it will be noted that the-tape T ismounted in case ID on suitable cross bars- 36' which are shouldered at 38 to properly center tape T of different-widths. With the cover member. Ifipivoted at the rear end of the case, it is -quiteapparen-t that the cover member may be moved to the raised or open position Without interfering with any of the adjustments of the machine and when repositioned by simply loweririg the cover, the machine will be in position to -operate.

The tape operating mechanism 39" including the tape feed and the cutting. shears are assembled into one unit which is easily positioned in the case: I O-and attached by means of screws 40 to bosses 42 integral with side walls 12' and I4"; This tapeoperating. mechanism comprises a U-shaped'fra-me 44-having-a base 4 I ,and vertical end wa'lls'43-and 45-in which isrotatably mounted wihorizontally disposed operating shaft 46. This shatt iaprovidedwitha sleeve 48 having ahub 50 to receive the masterfeed roller 52. Sleeve 48 is secured to shaft 46 by pin-54. J

Byreferring to the-Figs. 2,4 and 5 it will-be noted that the master feed roller is disposed slightly diagonally to the axis" of shaft: 4'6. In other words, the center major plane of the feed roller 52 is not'at right angles to theaxisof-sha-ft 46 thus giving it a slightly wobblingl motion as the"shait 4fi is rotatedr A compression spring 56 positioned between frame 44 and the sleeve 48 acts as= aebrake-andalso serves to maintain the master fe'ed roller 52 substantially in the center of the'tapriat all times; This special'positioning of the feed roller tends-to: cause a slightly transvense movementof the tape being fed over the moistening wick member 33, thus insuring a better moistening operation.

The base 4| is provided at its forward edge with a downturned lip 58 to which is attached a stationery shear blade 60 by means of screws 62. One end portion of blade 6|] extends outwardly through a slot 64 formed in side wall l2. A movable shear blade 66 is pivoted by pin 68 to the outer end portion of the stationery blade.

A stop pin 70 serves to limit the upward movement of blade 66. A coilspring 12 is so constructed and positioned so as to constantly urge blade 66 against blade 60 to facilitate proper cutting and to always urge blade 66 to open psltion. A finger 14 hinged to the outer end of blade 66 for limited oscillatory movement relative thereto by means of pivot pin 16 for operating the shear as hereinafter described. It will be noted that finger 14 is U-shaped in cross section and straddles the blade 66 and is free to pivot relative thereto through limited an les. When in the position shown in Fig. 4, finger 14 is secured against further downward movement relative to the blade 66 by the inclined end portion of said blade. When the crank handle 96 is below finger 14 it can raise the finger 14 out of its path of travel without moving the blade 66. Finger 14 extends through slots 15 and 17 formed in case l0 and cover It respectively.

The base 4| of frame 44 is slotted at 18 to receive the floating tension roller 80 which is rotatably mounted on a shaft 82 having flattened end portions 63 which slide in slots 84' formed in the side walls 86 of bracket 88 secured by screws 90 to the under side of base 4|. A V-shaped tension spring 92 rests on bracket 88 with its outer end portions resting respectively against opposite end portions of shaft 82 whereby the roller 00 is constantly urged toward the master feed roller 52. Shaft 82 can not rotate, but can move vertically in slots 84 to permit proper positioning of rollers with the tape therebetween whereby the tape is fed from the machine.

A tension spring 94 secured at its opposite ends to the end walls 43 and 45 is formed to extend in front of feed roller 52 and rest on tape T to maintain the tape in flat position after it leaves the feed rollers.

An operating crank 96 is mounted on shaft 46 for limited fre rotary movement by means of fixed end washer 98 and radially disposed pin I06 carried by the shaft 46. A pin I02 carried by the hub I94 of the crank which serves to engage pin I00 to drive the feed roller 52 to deliver the tape and also permit of a backward movement of the crank to permit the operation of the shears whereby the tape is severed.

When the crank is operated to move the tape from the machine the crank 96 strikes the finger l4 and moves it out of the path of travel of the crank 96, so that as much tape as is desired may be fed from the machine.

When it is desired to sever the tape the operator simply reverses the direction of movement of crank 96 until it strikes finger 14 and moves it downwardly to cause a shearing of the tape. The shear blade is limited in its downward movement after the shearing operation is completed so that the movable blade will be in position to be urged to its raised normal position by the action of spring 12. An arcuate guide member I06 is secured to U-frame 44 to direct the tape from the feed rollers outwardly and upwardly so that it will pass between lip 22 and wick 30.

In the operation of this machine the roll of tape is positioned on cross bars 36 in case l0 and the end thereof is passed between rollers 52 and 80. The operator by turning the crank 96 in a clockwise direction will cause the tape to be fed between lip 22 and the moistened wick 30 whereby the tape will be moistened. When the proper length of tape has been fed forwardly beyond the shear blade the operator reverses the rotation of crank 96 to the anti-clockwise direction to engage the finger 14 and force the movable shear blade 66 to the cutting position whereby the tape is severed. As the tape is pulled from the machine the inner end portion thereof is moistened.

The tape within the machine is now definitely separated from the moisture, and will not contact wick 30 until the next feeding operation is made by the operator.

Short or long pieces of tape may be fed from this machine at the option of the operator, and each piece will be freshly moistened from end to end during the current delivery operation and no moistened portion of the tape will be left in the machine.

What I claim as new and desire to cover by Letters Patent is:

1. In a tape dispensing machine and open top case, a cover member adapted to close said case and having a depending lip adjacent a tape delivery slot formed therethrough, a manually 0perable tape feeding and severing unitary member removably mounted in said case and operable .to deliver sections of tape through said delivery slot, and a spring actuated moistening wick adapted to contact and urge tape passing from said feed rollers against the depending lip of said cover member.

2. In a tape dispensing machine an open top case, a hinged cover member adapted to close said case and having an arcuate lip adjacent a tape delivery slot formed therethrough, a manually operable tape feeding and severing unitary member removably mounted in said case and including means operable to selectively deliver predetermined lengths of tape through said delivery slot, and a spring actuated moistening wick adapted to contact and urge tape passing from said feed rollers against the depending lip of said cover member.
